Milia or ‘white spots’ are small cysts formed of keratin, a protein found within the skin.  They appear on the top layer of the skin and can be found around the eyes or cheeks. They form when skin cells become trapped rather than exfoliate naturally. The trapped cells become walled off into tiny cysts that appear like white beads below the surface of the skin. As the surface is worn away, the tiny cyst may resolve on its own, though, intervention to remove the cyst may offer more rapid resolution.
Though they are not associated with acne or blemishes  but they can sometimes be uncomfortable and irritating. 

Milia are common in all ages and both sexes. They most often arise on the face, and are particularly prominent on the eyelids and cheeks, but they may occur elsewhere.
